Actually all declarations are hoisted. Trying to access variables declared with let and const before the declaration will hit the temporal dead zone and will throw.
Thank you for taking the time to read my article and to leave a comment. I did forget to include bigint and symbols. In regards to hoisting, only function declarations are hoisted. Function expressions do not get hoisted by JavaScript. When it comes to variables, var, let, and const are all three hoisted by JavaScript, but let and const throw an error, as Stoyan stated.

Few notes:
